I've just about finished a redesign of the TTC's rapid transit map. I felt that, aesthetics aside, it was sorely lacking in necessary information. I'd like to get all of your opinions and feedback on it before I release it.
Beautiful work! I love the details, e.g. the mode icons that reflect international standards while still keeping a Toronto look. And putting the CN Tower on there is genius.
In terms of the content, there are two planned GO-subway connections that the map doesn't really indicate: Downsview Park (for the Barrie line) and Bloor/Dundas West (for the airlink). Bloor station is on the map but it's not clear that there's actually a connection (which there will be). It's also expected that there will be GO connections at Eglinton & Caledonia and Eglinton & Weston/Black Creek, but maybe you're not showing these because they haven't been formally announced.
You could maybe simplify the streetcar map by removing the two routes that only run in rush hours. I'm not sure if the 7 daily trips of the 508 really warrant making the map messier!
It would be nice to have some sort of indication of the stops on the LRT lines. If labelling all the stops would make it too cluttered, you could follow Boston's model and put in a dot for each LRT stop, but only put in labels for the important ones.
In terms of design, is it really necessary to use the double-circle symbol at all connection points? It makes sense at St. George because you've drawn the two subway lines in parallel, but it looks quite odd at Eglinton West and Finch West, for example, where both of the circles are placed on the same line. It seems like a single circle where the lines cross would do the job just as well (especially since you aren't using a single circle to indicate anything else).
Also, a minor quibble, but the TTC subway map captures the fact that the St. George connection is much more direct than the Spadina connection, while your map seems to imply, if anything, that the Spadina connection is more direct (because you show the two lines crossing at Spadina).
More generally, the one drawback that I see is the scale -- your map contains a huge amount of white space and the text labels are very small. If you compare it with the current subway map, it's not nearly as legible from a distance (even though it's much more beautiful) and would have to be printed at a much larger size. I almost feel that if the map is going to be this large, and you're going to have such wide swathes of empty space, maybe you should make use of the space by also including the 10-minute bus network or something (although I know that's a whole 'nother project and it would no longer be just a rail map then).
That's a lot of comments, but it's only because I think the map is excellent and would like to see it get even better!
